RESILIENT SHOE.

To allwhom timay coment:

Be it known that we, GEORGE J. WINTER and CHARLES S. DIEBoLT, citizens of the United States, residing in Buffalo, in the county of `Erie and State `of New York, have invented new and useful Improvements in Resilient Shoes, of which the following is a specieation.

This invention relates to that class of shoes which are provided with means whereby the same are rendered waterproof and resilient and' itis the object of this inventionto provide a shoe of this character which is-low in cost, capable of being easily manufactured and which will not 'only adapt itself to the conformation ofthe foot but? also provide a resilient tread and protect the bottom of the foot from moisture and extremes of temperature.

lIn'the accompanying drawin s:

Figure 1 is a vertical longitu inal section of a shoey constructed in accordance with our invention. Fig. 2 is a bottom plan view of the intermediate or protecting layer of the shoe which is interposed between the outsole 'and the insole thereof. Fig. '3 is a cross section of the shoe taken on line 3-3, 11. Fig. 4 is a horizontal section taken on the correspondingly numbered line in gimilarfcharacters of reference indicate corresponding parts throughout the several YBWSQF?.

i The general construction of the shoe may be varied as to details inasmuchV as our im provements are'capable of use in shoes of various kinds. In the drawings our invention is' shown ap lied to one form of shoe which'is suitableY or receiving our improve- Vments and as there shown the same consists essentially of an upper :1, an' insole 2 arran 'i below the upper, la shank'piece 3 engaging with the under side ci the linste or central part .ofthe insole, and an outso e 4 Varranged below the insole and shank piece. Along the :mar

al vportion of the frontpart of the insole e same is provided with' a welt 5 which is secured in accordance with the usual and well known Goodyeas'sttch 6 Patented Sept. 2, 1919.

to the upper and insole so thati the underside of the insole is raised abovethe level of the underside of the welt.

One feature of our improved shoe consists in arranging a layer 7 of impervious material, such as rubber, between the u per side of the outsole and the underside o the welt and the insole, this intermediate layer being secured at its margin to the welt and outsole in any suitable manner, for instance, by means of a marginal row of stitches 8, as shown in Figs. l, 2 and 3. This rubber layer therefore not only serves to cushion the underside of the shoe but also protects the foot against excessive coolness in the winter time and undue Warmth in the summer time as well as preventing cranking of the insole.

Inasmuch asthe underside of the front part of the insole is raised above the underside of the Welt, an up r air space 9 is formed between the insolldeand the intermediate protective layer at the front ends of these members which further cushions the step of the foot and retards the passage of moisture through the same from the underside of the shoe to the foot as well as protecting the foot from undue changes in temperature.

In order to still further increase the resilience of the shoe and protect against ball part of the shoe in front of the instep` thereof, these lower front and rear air spaces being se arated by a transverse partition or rib 12 w ich is curved and adapted to register with the joint between the toes and the ball of the foot resting upon the sole or bot-V tom of the shoe. By this means the top of the insole is capable of conforming more "readily to the surface on 'the underside of heel welll lower as olea-ry shown: in

the foot, thereby rendering the shoe more comfortable in addition to yieldingly supportingthe foot.

It will be noted that by the ein loyment of these additional air spaces on te underside of the impervious intermediate layer air cushions are formed between the upper and lower sides of the layer und the insole and outsole above and below the same, thereby obtaining the maximum cushioning eifeot for the foot on the front part of the shoe as Well as guarding to the utmost degree against the transmission ofany moisture or undue temperature through the front part of 'the shoe bottom to the foot.

Another eature of our improved shoe resides in the construction of the heel so as to render the same resilient, easy to repair in oase of Wear and also to protect the rear of! foot resting' thereon against undesirable temperature and moisture. As shown in Figs. 1 and 4, this improved heel comprises an elastic body which is arranged under- Heath the heel portion of the shoe bottom and consists of a marginal upright wall 13 which engages its upper edge with the undersideof the outsole, a horizontal flexible diaphragm 14 arranged within this wall between the'upper and lower edges thereof and connected with the inner vside of the same, an upper' boss 15 arranged centrally on the up er side of the diaphragm and engaging ivi the underside of the outsole and a lower boss 16 arranged centrally on the un derside of the diaphragm and pnojeeti-ng downwardly therefrom. The Wall, diaphragm and bosses of this heel body may be constructed of any suitable resilient ma terial but preferably of rubber or a rubber Composition. The heel body may be secured to the sole in any suitable manner, for instance, by means of upright nails 17 which pass through the body of the heel `and engage the heads at their lower ends with Vmetal anchor disks 18 which are molded in ytlrex'heel body While the Upper ends of these 4nails engage with adjaeent parte 'of the shoe y lthovundorside of this heel body is engaged by a liti?" 19, prefewbly of leather `or other suoabie materiell', which s'adaptod to take #he wear and can be 'renewed vom time to time-when worn out. This lift engages its nialtgfhal part with llower edge of the while 'the central an: thereof yenits oppor sidewith't e loworg of oreeeunin this detaohablyv toI the hooi body and' shoebottomrthe pre opted means for' this purpose vwh'eh arev .shown `in the nrownigsfcoggise a @plurality dimils 20 weiem body and the shoe bottom and arranged out of line with the nails which secure the heel body to the shoe bottom, thereby permitting of removing and renewing the lift Without disturbing the heel body.

The upper end of the upper boss projects slightly above the to rof the heel Wall when this body is remove. from the Shoo bottom whereby upon applying this body to the shoe bottom the diaphragm will be deflected downwardly slightly and in a Milly ieXed condition when the heel is in p are, thereby insullfingifa resilient support for the heel of the foot.

In this form'A4 oi heel theA filoni-'bili die phragm together with the wir spaces 21, 22 termed between 'opposite sides of Ythe same and the sole and lift together form a cushion support for the heei andy enables heel pressure to be elastieally sup ortod while Walking, while at the same e mifnn sulicient firmness in the heel dueitotlwe'soli( portions provided by the bosses and. the Walls of the heel body whichl insure imness in the step.

Ofur improved onshioninzg and protecting means coin'be produced by 'the use of oompmratively low priced molds and theenne oanbe 'applied to shoes now ifn.` enoralruse without requiring any s pe'eial skull Aortllnis purpose; thereby enafbrl these improvements to be incorpora/ted 1n fashoewlthdut undue added Cost.

By reason voli the 'elssttowyer between' the--` insole and outsolel andthe elastioheel'lody the outsole and liiit ivre eausedto wearfnmre evenly and they also prevent exeessirre spiration of the foot. The arch fof the ot is also properly supported and pnestnreflon the joints is relieved. Furthermorea shoe constructed in accorda-nee without? invention will not produce anydisagroeaxl' squeaking While in use, the same isf abaolutelyywaertight and in addition is a safeguard agmiist' elsdtrie `slfiorelrs ier the ipmonywer' the shoe inasmuch `as the 'ereof serve as insulating members Whiohsfpnevent hex :passage ithroltghItheahoe.
